Single slips were often used on double track lines to incorporate a trailing crossover into the access for a siding, goods yard etc. The clever geometry of this range enables the modeller to easily create convenient, complex and aesthetically satisfying track formations using combinations of small, medium and large radius turnouts and crossings. Despite a low visible rail height of just 1.4mm, all brands of N Gauge model locomotives will run on this track. The ingenious rail section of PECO 55 combines strength and durability with a highly realistic appearance and uses the same universal rail joiners as Code 80; the geometry of this range has been cleverly designed to make it easy to build convenient, complex and aesthetically pleasing formations.
